At least for the foreseeable future‚ this planet is the only home we’ve got. It would be useful to know‚ then‚ whether it will continue to be habitable. Sometimes contemplating the future just means wondering whether it will snow tomorrow‚ or whether it will be a hot summer this year. We can think bigger‚ though. What will the climate be like a hundred years from now‚ or a thousand or a million? Will the greenhouse gases in our atmosphere ever reach an upper limit and start to diminish? Will our

approaches the carbon bearing the halogen from the back side. As the reaction proceeds‚ a bond begins to form between the nucleophile and the carbon while the bond between the carbon and the halogen begins to break (this is the transition state). The reaction is complete when a covalent bond has formed between the nucleophile and the carbon and the halogen has been removed as a halide ion. This process is accompanied with an inversion of stereochemistry at the targeted carbon center. In this

Reduction of Carbon dioxide greenhouse gas by microalgae fixation leading to biomass‚ biochemical and biofuel production After recognizing that the first and second generation of biodiesels is from sugar‚ vegetable oils and lignocellulosic biomass‚ microalgae are now known as the ‘third generation of biodiesel’. As many studies have told us that microalga is a promising organism for mass production of biomass and biofuel which are renewable and environmental friendly. Microalgae have a higher

barrier and specific transport proteins exist to carry pyruvate and fatty acids into the matrix. Once inside the matrix‚ pyruvate and fatty acids are converted to the two carbon compound acetyl coenzyme A (acetyl CoA). For pyruvate this involves a decarboxylation step which removes one of the three carbons of pyruvate as carbon dioxide. The energy released by the oxidation of pyruvate at this stage is used to

Experiment #3 Mark A. Bruder 07. T.A. Michael Hall Alkanes: Chlorination Introduction: The purpose of this experiment is to determine the reactivity of hydrogen atoms on a carbon chain using free radical chlorination. In this experiment 1-chlorobutane will be chlorinated with the combination of sulfuryl chloride and ABCN as an initiator to produce the chlorine radicals. The combination of 1-chlorobutane and sulfur chloride will produce four dichlorobutane
